Okay, so we knew Rihanna and Chris Brown were working together on her song "Birthday Cake," but now it turns out that they've also collaborated on Chris Brown's song "Turn Up the Music." They've both just been released for our listening pleasure, if you could call it that, and here they are.

Their version of "Birthday Cake" is positively painful. Brown's first words are "Girl, I wanna fuck you right now. Been a long time, I've been missing your body." *shudder* "Turn Up the Music" is a bit more benign, but it's hard not to have very mixed feelings about whole enterprise. If only they didn't sound so damn catchy together. What do you think? Can you listen without cringing?
